Question

Calculate the weight of CH4​ in 9Lt cylinder at 16 atm and 27oC.

​

Answer 1

Answer:

93.6 g

Explanation:

Let the weight of methane (CH4) be W gm

Molecular mass of methane = (CH4) = 16

Volume = 9L

Temperature = 27℃ = (273 + 27) K = 300K

Pressure = 16 atm

No of moles = wt / Mol x wt  = W/16

R= 0.082 L atm mol -1 k -1

Applying ideal gas equation, we have

PV=nRT

16 x 9 = W/16 x 0.082 x 300

W/16 = 144/24.6

W = 16 x 5.85

W = 93.6 g
